An ejector in the form of a T- bar 33, having a spring 34 interposed'between its head and a fixed part of the form 19, has a hooked end 33, adapted to engage a springcontrolled latch 35, and afiords means for antomatically removing the can-body from the form and operates as follows: The ends of the T-head project through slots 36 in the sides of the form 19 and are normally held back by the latch 35 at a point beyond Where the metal is folded over the form. The arm 37, depending from the pivot of latch 35, engages the projection 38 upon the guide 26, causing the latch to rock downward against the spring 39 and release the hook 33 of the T- bar 33. Under the impact of the spring 34 T-bar 33 is thrown forward, the projecting ends of the head sliding of the metal and stripping the can-body from the form and depositing it in any suitable receptacle. A spring 40 in the path of the projecting end of the T-head of the bar 33 serves to return the bar to its normal position and lock it with the latch.
